That exactly. Which is probably the same thing that several others have pointed out..
A 100$ shirt will have huge logos all over the place because the market segment it targets are people who can "just" afford it and want to signal other people who can't.
A 1000$ shirt will have little to no logos and will be distinguished only by "others" who can spend as much, because if you wear 1000$ shirts why would you care signalling to the person who can "just" afford 100$ shirts that you have so much more? You may care to signal this to other 1000$ shirt owners but then maybe you just don't care about signalling via clothing ;)
